*Prior to treating children, adolescents, and adults with CNS stimulants, including DYANAVEL XR, assess each patient’s risk for abuse, misuse, and addiction. Assess for the presence of cardiac disease (ie, perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam). Assess the family history and clinically evaluate patients for motor or verbal tics or Tourette's syndrome. The recommended starting dose is 2.5 mg (1 mL) or 5 mg (2 mL) given orally once daily in the morning. Dosage may be increased or decreased in increments of 2.5 mg (1 mL) to 10 mg (4 mL) per day every 4 to 7 days. Daily dosage above 20 mg (8 mL) is not recommended.
